CELESTIAL PHENOMENA, FOR FEBRUARY, 1838.

METEOROLOGICAL JOURNAL,

FOR DECEMBER, 1837, AND JANUARY, 1838.

The very low state of the thermometer has not been equalled during the past eighteen years; upon reference to our Journal for January 1820, we find two remarkable coincidences, viz. that during the previous days of the week, the wind had been, as now, from the N.E., changing on the morning of the 15th to the S. W., and the thermometer falling to 1o, it is singular enough that just the same date of the present year marks the same low degree of temperature, and precisely the same change of the wind.

The still lower state of the thermometer on the morning of the 20th, when it was 5° below Zero, or 37° below the freezing point, has not been equalled since the 25th December, 1796, when it was one degree and a half lower, viz. six degrees and a half below Zero, which we believe to be the lowest degree ever registered in Great Britain.

The feeding drum is furnished with a wheel L, having ninety teeth of half-inch pitch, and it has also fifteen stop pins accurately pitched, which regulate and govern the advance or feeding in of the correctness of the cloth and the material to be printed, and upon which the joining of the pattern depends; M, is a double pinion or two pinions fixed upon the same axis; the small pinion has twenty-four teeth, and is always in the gear with the wheel L; the large pinion has forty-eight teeth, and is
